RAZOR BLADE HOLDER Edward Olszewski, Detroit, Mich.

Application July 24, 1943, Serial No. 496,259 2 Claims. (01. 51-218) Myholder is of the kind that will accommodate razor blades of the wafer,double edge type. The purpose of my invention is to provide a device inwhich a blade may be held securely and firmly while being sharpened byhaving its cutting edges rubbed against a flat, slightly abrasivesurface such as glass, honing stone and the like.

Another purpose of my invention is to provide a holder in which theblade may be placed easily, quickly and safely and from which it may beas easily, quickly and safely removed.

I shall now describe my invention with reference to the accompanyingdrawing in which,

Fig. 1 is a perspective view of my holder with the blade holdingelements turned down;

Fig. 2 is a side elevation of one of main component parts of my holder,said part being shown somewhat enlarged for better illustration;

Fig. 3 is a side elevation of another main component part of my holder,also enlarged;

Fig. 4 is a perspective view of my holder slightly modified, with theblade holding elements turned upwardly;

Fig. 5 is a top elevation of my holder with a blade in position forsharpening;

Fig. 6 is a side view of a modified locking element, being a part of myholder.

Similar numerals refer to similar parts throughout the several views.

Generally speaking, the holder consists of a handle it! and a transversemember H for the support of a blade, and may be made of metal, plasticor some other suitable material. As shown in the drawing it is composedof two main parts [3 and I4, said parts being clamped together by meansof a screw l5 passing through hole It in each of the two parts. As eachof said parts is depressed on what is its inner surface, a slot I! isformed automatically when said parts l3 and I 4 are affixed to eachother.

The transverse member ll includes a base 30 and a rectangular bed 3|,the latter being narrower than the base and narrower than theconventional two-edged razor blade. The purpose of this construction isto have the edges of the blade extend beyond the sides of the bed asshown in Fig, 5.

Mounted on the depressed surface of part i 4 are two members It? and 26,being substantially circular in shape and provided with intermeshingoteeth 2|. As the teeth are restricted to a part of their respectivecircumferences, the rotary motion of members l9 and 20 of which they arecapable, is limited. Extending tangentially from the rim of each saidmember, but in opposite directions,

are holding fingers l2, which are normally disposed parallel to thelongitudinal axis of the bed and close above the opening of slot H.

Member 20 is provided with a substantially radial lever 22 having ashoulder 22a normally disposed below the surface of bed H3. The leverserves to control fingers I2. When, as shown in Fig. 3, the lever ismoved in the direction of the bed, it causes fingers l2 to swingupwardly in a converging arcuate motion, while shoulder 22a enters slot[1, as shown in Fig. 3. When the lever is brought down, the shoulderrecedes from the slot, while fingers l2 revert to their normal position.

As a means of locking the shoulder and fingers against movement, I havedevised a bolt 24, bearing against a compression spring 21 within arecess 25 in member 13. A retaining plate is indicated by a numeral 26and retaining pins by numerals 28. When the lever is brought down, thebolt is forced in by a transverse flange 23 on lever 22, but comes backimmediately into the path of the flange on its return.

Another locking device is shown in Fig. 6. This consists of a sleeve 33ending in a bolt 34 and sliding on a horizontal flange 35 of lever 35.The bolt may be shifted manually into a recess 31 in the side of myholder 38. Numeral 39 indicates a blade holding finger.

I have discovered that the blades may be sharpened quicker when the sideedges of bed l8, instead of being level are wavy or corrugated. I amtherefore showing a bed with such corrugations in Fig. 4.

I shall now describe the operation of my holder: In order to place ablade on bed N3, the lever 22 is moved upwardly to have fingers l2 swingfrom a horizontal position, in an arc towards each other. A conventionalblade having a central longitudinal aperture is placed on bed so thatthe fingers project through said aperture. The lever is then moveddownwardly, causing the fingers to swing back to their initial positionand to clamp down the end portions of the blade, as shown in Fig. 5.

It is assumed that the lever has been brought downwardly far enough tobe caught by the movable bolt 24, which holds the lever in place. Whilethe blade is thus clamped down to bed 18 by fingers l2, it may besharpened by being rubbed against a suitable fiat surface as alreadyexplained herein.

When it is desired to remove the blade from the holder, the lever ispushed upwardly, past the yieldingly projecting bolt. The shoulder 2212on lever 22 will abut the blade helping to push it off the bed, as shownin dotted lines in Fig. 3.

It is obvious that some changes in the construction of my holder arepossible although such changes may be within the sphere of my inventiveconcept. What I, therefore, wish to claim is as follows:

1. A holder for razor blades having a central longitudinal aperture,comprising a handle, a cross member thereon, having an inwardly archedbed to support a blade, said bed having a centrally located longitudinalslot designed to be in register with the aperture in the blade, twogeared wheels in said slot at right angle to the bed and in mesh witheach other, a tangentially disposed clamping finger extending from eachwheel in a direction opposite to that of the other, lever means toactuate said fingers by means of said wheels to clamp the end portionsof the blade from inside its central aperture.

2. A holder for razor blades having a central longitudinal aperture,comprising an inwardly arched, substantially rectangular bed for ablade, said bed having a centrally located longitudinal slot designed tobe in register with the aperture in the blade, two flat memberspivotally mounted within the slot, each having a plurality of teeth inmesh with the teeth of the other, a clamping finger on each member, thefingers extending in opposite directions and being normally disposedparallel to the surface of the bed, a lever projecting from one of saidmembers and out of the slot to impart an oppositely rotary motion tosaid members to cause the fingers to clamp the end portions of the bladefrom inside its central aperture.
